Applipationfiled'Maroh 2 1, 190a. semi No. 9,490. mamas.)

To all whom it may concern.-

Be it knownthat I, FRANK A. BURNHAM, a-

citizen of the United States, residing at Cle'ves land, in the county of Cuyahoga and State of Ohio, have invented certain new'and useful Improvements in Printing-Presses; and I do declare that the following is a full, clear, and exact description .of the invention, which will enable others skilled in the art to which it appertains to make'and use the same.

My inventionrelates to improvements in printing-presses; and'the invention consists in what is shown in the drawings as an attachment to a well-known style of Gordon press, the said attachment comprising an electric motor and a support therefor and power connections, all substantially as hereinafter set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a press equipped with my new attachments. Fig. 2, Sheet 2, is a rear elevation of the press and new equipments thereon, as inFig. 1. Fig. 3' is a sectional elevation on line 3 3, Fig. 2, of a portion of the press and a plain elevation of the motor and the motor-bracket fixed to the press. Fig. 4 is a sectional elevation on a line corresponding substantially to 4 4, Fig. 3, looking to the left and/showing sections of the several pulleys connected with the bed-shaft and forming a part of my new attachments. Figs. 5 and 6 are small details, as hereinafter fully described. I

In the invention as thus sho wn it will be seen that the press itself is complete and operative substantially as hitherto and is not really changed in these particulars, although it has necessarily undergone modification to adapt it to the new and added features, as shall be seen,- 1

A represents the main and stationary frame of the press, and B the bed, which is'pivoted to rock back and forth on the bed-shaft C.

D is the usual crank-shaft, on which is the combined band and fly wheel E. Hitherto this has been a fly or balance wheel only, having no other mechanical function or purpose; but in my improved organization I do not divest the said part of its character as a balance-wheel, while I convert it into an ac 'tor. jquired, to carry the said brackets, as they are tive member in the chain of poWer-comm'unieating mechanism between electric motor G and the crank or power shaft C. From the said shaft C, hence to the other operative parts 5 5 of the press, thereis no change whatever introduced'by my present invention, and therefore certain of the details of such unchanged mechanism have been omitted from the drawings as unessential to this application.

The motor G is designed, of "course, to be the medium for actuating or driving the press and is supported in a position at the back of the press, where it is practically out of the way and yet is in the most advantageous place for connecting up with the parts to be driven.

The immediate support for the motor consists of two substantially T-shaped brackets H, having one arm each provided with a boss 7t, sleeved on the bed-shaft C, and the other arm with a boss it, supported or sleeved on cross shaft or rod J, while the stems of the brackets H stand out horizontally and support the platform 712, on which rests the mo No auxiliary means are therefore readapted to parts already in the machine.

Ordinarily the bed-shaft C is limited to the immediate outside of the machine, where it affords a pivot for the bed-standards. This it does here; but for the purposes of my invention a new shaft C is required to adapt it to the additional or added mechanisms supported on'its extremity, as seen in Figs. 2 and 4. Thus the motor-shaf t carries a set of conebelt pulleys 2, which are matched by an exactly-similar but reversely-arranged set 3 on shaft C, and a belt N runs over these pulleys or sets of pulleys and is governed for speed according to its position thereon. The'pulleys 3 are shown here as integral with asleeve L on shaft C and adapted to rotate thereon, the saidsleeve having on itsouter end'the pulley 4, through which and belt or band M 95, power is conveyed to the large drive-wheel E. An idler 6, carried on arm P and controlled by rod '7 and lever 8, serves to fix or relieve the operative tension of band Mg as seen in Fig. 1. The lever 8 has a hub pivoted on a stud or projection 9, Figs. 5 and 6, and the rod 7 is pivoted on its hub relatively above s I V I ei ifi'si its own pivot-point about as shown in,Fig..1, and the neck of the said rod is so bent as to accommodate the throwing of the lever 8 past its dead-center, and thus causes it to hold that relation and tighten'the belt or band and set the press in motion; but a throw of lever 8 back to the other side of its center causes the idler to relax the belt and the press stops. The hub of lever 8 has a stop 10, which plays between two lugs 11 and 12, which .are also the limits of its movements.

It will be seen from the foregoing that the motor is the power medium attached to thepress itself, so that each and every press has an independent source of power as a self-contained element, and when the press is stopped In assembling the various parts either upon a new or old press the bed-shaft pro vides a perfectly-alined center from which to support brackets H, thus assuring aperfect alinement for the brackets, the motor there-.

on, and the pulleys without extra tapping, drilling, or other labor.- .The brackets H are adjustable on shafts Cand J to accommodate narrower or wider platforms h and set-screws in the bosses h are used to fasten them in fixed position and to prevent side sliding thereon. I

. What I claim is- 1. The press-frame and a power-shaft andan extended bed-shaft thereon, a platform supported on said frame and bed-shaft, a motor on said platform, and power-transmitting mechanism on the bed-shaft extension having power-connecting means with both said power-shaft and motor, substantially as described. r

'. 2. The press-frame and an electric motorthereon having a shaft with pulleys, the bedshaft of the press and pulleys. thereon, and a,

belt connecting said pulleys, the crank powershaftand power -transmitting mechanism thereto from the said bed-shaft, substantially g as described.

. 3. The press and the electric motor,the bed shaft of the press and power-conveying pul leys on one end thereof outside the press- ;frame and means to convey power from the motor to said pulleys, the main crank-shaft of the press and a combined band and bal-' ance wheel thereon, and a beltto drive the same engaged over a pulley on the bed-shaft, substantially-as described.

4.. In a press substantially as described, the

bed-shaft and a plurality of power-conveying pulleys sleeved thereon and adapted to different belt connections, the crank-power and a combined fiy and band wheel on said shaft arranged to be drivenfrom the power-convey- 7o ing pulleys on the bed-shaft, substantiallyas described.

5. In aprinting-press the crankpoWer-shaft and a band-wheel fixed thereon, the 'bedshaft and a sleeve on said shaft provided with 7 5 a plurality of pulleys for different belt connections and one of saidpulleys in line with said band-wheel, in combination with an electric motor supported on the press-frame, and

a set of bands to carry the power from said motor to'said band-wheel, substantially as described.

. 6. .The press hav ng a bed shaft and a crankshaft, a bandewheel on the crank-shaft and a pulley sleeved on the bed-shaft, a band over said band wheel and pul1ey,an idler to tighten said band, and a lever-and-link connection extending'to the top of the press for controlling the idler, substantially as described.

7.- Themain frame of the press, a power- 0 shaft thereon, a bed-shaft having an'extension at the side of 7 said frame, a set of brackets supported on said bed shaft and frame, a motor supported by said brackets, and powertransmitting and speed-controlling mechanism for said power-shaft supported in said bedshaft extension, substantially as described.
